Effect of organic fish and inorganic fertilizers on the growth and yield of lettuce “Batavia” in aeroponic system


Author(s): Nguyen Trinh Nhat Hang, Nguyen Tuan Phong and Tran Thi Thua

Abstract: Study on the effects of organic fertilizer decomposed from fish waste combined with inorganic fertilizer on the growth and yield of lettuce Lactuca sativa "Batavia" in an aeroponic system was carried out at Tien Giang Center of Applied Research and Science Technology Services in 2022. The study aimed to determine the effectiveness of the organic fish fertilizer solution combined with the inorganic fertilizer solution on the promotion of plant growth and yield of lettuce “Batavia” in an aeroponic system. The experiment was arranged in a completely randomized design (CRD) with five treatments and four replications. The five treatments of fertilizers included (T1): 3000 ppm organic fish; (T2): 2500 ppm organic fish + 250 ppm inorganic; (T3): 1500 ppm organic fish + 500 ppm inorganic; (T4): 750 ppm organic fish + 750 ppm inorganic; (T5): 1000 ppm inorganic (Control). All the treatments of organic fish fertilizers were supplemented with microorganism 0.1% EM2. The results showed that lettuce “Batavia” grew well in the aeroponic systems when treated with 1500 ppm organic fish + 500 ppm inorganic and 2500 ppm organic fish + 250 ppm inorganic which gave high results in terms of total number of leaves (32.5 g; 32.05 g); plant weight (122.45 g; 115.81 g) and yield (3.06 kg/m2; 2.90 kg/m2), respectively compared with the other treatments.
